Nano Touch Dimmer Switch Kit with Arduino Nano + Sensor
Arduino Nano Touch Dimmer Switch Kit: Master Capacitive Touch and PWM Control
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine controlling a light with just a touch — no buttons, no switches. With this kit, you’ll build a capacitive touch dimmer that cycles through four brightness levels using an Arduino Nano, a TTP223 touch sensor, and a MOSFET. It’s a perfect introduction to sensor interfacing, PWM, and real-world electronics that you can use every day.
What You'll Build
A sleek, touch-controlled LED dimmer that responds instantly to your fingertip. You’ll assemble the circuit on a breadboard, upload the code, and see the LEDs smoothly transition between off, low, medium, and high brightness with each tap. This working prototype can be mounted into a lamp base or used as a standalone sensory light.
What You'll Learn
- How capacitive touch sensors work and how to interface the TTP223 with Arduino.
- PWM (Pulse Width Modulation) to control LED brightness smoothly.
- MOSFET switching fundamentals — using an IRF540N as a power switch.
- Circuit debugging and breadboard prototyping techniques.

Who This Kit Is For
Perfect for CBSE Class 11-12 students exploring physics practicals, B.Tech ECE/EEE freshers building their first sensor circuit, ATL Tinkering Lab workshops, and hobbyists looking for a parent-child weekend project. If you’re curious about how touch screens work or want a quick, satisfying electronics build, this kit is your starting line.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to chat with your AI companion, which has the full circuit diagram and code; if you need human help, WhatsApp us directly and we'll walk you through the fix.
Do I need to know soldering?
No soldering is required. Everything plugs into the included breadboard, making it safe and easy even for young builders.
Can I use this to dim a 12V LED strip?
Yes, the IRF540N MOSFET can switch higher voltages and currents; simply connect the strip and external 12V supply, and the touch dimming logic stays the same. The AI companion has a wiring guide for that upgrade.
What if the touch sensor doesn’t respond?
First check the sensor’s jumper setting and breadboard connections. The AI companion includes a dedicated troubleshooting flow, and our WhatsApp team is ready to help if needed.
TTP223 capacitive touch sensor dims LED via PWM through a MOSFET. Cycles 4 brightness levels on each touch.
